-==== Try to open a pass-all rule ====

-Add a pass-all rule at the top for that VLAN on pfSense and enable logging.

-If this allows this through then go through each subsequent rule to see if there is a problem.
-==== Check ARP tables ====
-Navigate to **Diagnostics -> ARP Table**.
-On your client, when you try and ping pfSense on 192.168.1.1, you should see your MAC in the ARP table.
-Check the MAC address is correct, i.e. matches up with pfSense MAC address.
-If the MAC address does not match the pfSense MAC address:
-  * There may be an entry for the IP in the ARP, so try to delete it.
-  * The system should automatically add this in again correctly.
-==== Check the Firewall Logs ====
-Check firewall logs at **Status -> System Logs -> Firewall**

-Check:
+If you are having issue make sure you disable any firewalls you have running on the pfsense client boxes … once you have your network configured you can enable them later.

-==== Solution ====
-  * **Servicess -> SquidGuard Proxy Filter -> Common ACL -> ALL to allow**
-  * May need to refresh the browser cache:
-    * CTRL F5
-    * CTRL+SHIFT+r
-    * SHIFT+reload button
-  * Might need to turn off support for the newest and most secure connection protocol, TLS 1.3.
-    * In Firefox
-      * Type **about:config** in the address bar and press Enter/Return.
-      * In the search box above the list, type **TLS**.
-      * Double-click the **security.tls.version.max** preference to display a dialog where you can edit the value from 4 to 3 (or in other words, from TLS 1.3 to TLS 1.2).
-      * Then click **OK**.
